So I painted a gig a little while back and it was super hot, but then rained, and my paints got rained on before I could get them covered. I store them lids off in paint trays. I pulled them out today to make sure everything was ready for a gig this evening and some of them are still super squishy. Any advice? What can I do to fix them?

We use a food dehydrator for our mooshy, squishy face paints. The next morning, they are pristine. We each have three pots of white and two of black and we each swap out the paint when it goes all blarfy.

I prefer the glycerin based paints. Paradise, Snaz, etc. The only time I get mooshing is when it 123,000 degrees outside or if the temp is normal and I accidentally set a cake in the direct sun. Placing them in a cooler spot for a while helps tremendously. I usually set them on top of my cooler, under my table (which is covered by a big lovely table cloth) and refrain from using them for a while.
